ALLAYS WETTABLE SUPERABSORBING MATERIALS Russian patent published in 2005 - IPC

FIELD: sanitary and hygienic facilities.

SUBSTANCE: invention provides processes for manufacturing allays wetted superabsorbing materials characterized by afloat time below 30 sec and causing surface tension of salt solution by less than about 30%. These processes envisage treatment of superabsorbing material with surfactant solution, which surfactant has at least one functional group capable of chemically reacting with superabsorbing material and at least one unreactive and hydrophilic functional group. Surfactant is deposited onto superabsorbing material when functional groups on the surface thereof are activated. Invention also disclose allays wettable superabsorbing materials such as fibers made according indicated processes as well as disposable absorbing articles containing above allays wettable superabsorbing materials.

EFFECT: enabled manufacture of articles with better liquid distribution properties.
